It's normal for your period blood to vary in consistency throughout the cycle, sometimes appearing thinner and more watery, especially on the first or last day of your period. However, persistent watery period blood can be caused by several factors, including:
- Hormonal shifts: Changes in hormone levels, particularly low estrogen, can lead to thinner blood. This could be due to starting hormonal contraception, approaching menopause, or even an eating disorder or excessive exercise.
- Early pregnancy: While uncommon, watery period blood could be an early sign of pregnancy, as hormonal shifts in the early stages can affect the menstrual flow.
- Other factors: It's important to note that watery discharge, especially if it's clear or white, is often related to cervical mucus and doesn't necessarily indicate a problem with your period.
If you experience unusual changes in your period blood consistency, especially if it's accompanied by other symptoms like heavy bleeding, pain, or unusual discharge, it's always best to consult a healthcare professional to rule out any underlying medical conditions.
